Corpus Christi, Tex. Filed May 6, 1963, Ser. No. 278,15 3 Claims. (Cl. 15602) The present invention relates to brushes, and more particularly to brushes of the type being used in the barber shop and commonly called neck dusters. Normally, powder is supplied to a neck duster by the barber. The present invention primarily concerns itself with providinga neck duster with its own supply of powder which may be dispensed by the brush automatically as it is being used.

Another object of this invention is to provide a neck duster which may be inexpensive to manufacture, durable and easy to operate.

A further object of this invention is to provide the neck duster with a handybrush handle appropriately shaped to tit a barbers hand.

Another object of this invention is to provide the neck duster with a brush handle and means for dispensing powder.

Another object of this invention is to provide a powder container in the handle and means for dispensing powder from said container.

An additional object of this invention is to provide the neck duster with a flexible tube which may supply powder from the powder container in the brush handle.

A further object of this invention is to provide the tube with openings from which powder may be dispensed from said powder container.

Another object of this invention is to provide the neck duster with an adjustable flexible tube which may act as a powder supply regulator. When the container is filled the tube is pushed lower into the brush handle, and as the powder container becomes empty the tube is pulled out to regulate the proper amount of powder to be dispensed.

Another object of this invention is to provide the ileXible tube in the brush handle with a perforated head at one end thereof and a tapered cone-shaped member at the other end.

This invention also consists in certain other features of construction, and the combination and arrangement of parts, to be hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

In describing the invention in detail, references will be made to the accompanying drawings, where like character numerals denote like or corresponding parts throughout the several views, in which:

FIG. 1 is a side cross sectional view of the present invention;

FIG. 2 is a perspective view partly in cross section;

FIG. 3 is an enlarged detail of the end of the tube end; and

FIG. 4 is a modification of the tube.

It is to be understood that the present form of disclosure is merely for the purpose of illustration, and that there might be various modifications thereof, without departing from the spirit of the invention as herein set forth.

Referring now more particularly to the drawing, the powder duster 10, shown in FIG. 1, made in accordance with the present invention, comprises, in combination, the brush handle 11; the powder container 12; the container cover 13; the brush bristles 14; the powder dispensing tube 15; and the dispensing opening 16 in the dispensing tube.

It can be seen from FIG. 1 that the brush handle 11 ICS may consist out of an elongated cylindrical hollow container 12 having an open end 11a which may be provided with an external thread 11b. The brush cover 13 may be provided with an internal thread 13a in its circular flange 13b. By means of the internal thread 13a the cover 13 may be threaded upon the outer thread 11b in the cylindrical handle 11 to securely close the container 12.. A quantity of tine talcum powder may be iilled into the container 12 through its open end 11a before screwing thereto the cover 13. A plurality of circular grooves 17 may be filled in the closed opposite end 11e in the handle 11 to receive the bristles 14 sub` stantially as shown.

To promote the delivery or the dispensing of powder P from the container 12, there may be provided a slim flexible pipe or tube 15 preferably made out of flexible rubber or plastic with one end thereof 15a being open to the powder in the container 12, while its opposite end (extending beyond the container 12 on the outside) being closed and carrying a number of ne holes 16 (see FIG. 3). The slender tube 15 is passed through a hole 18 in the closed end 11o in the handle 11.

FIG. 4 shows a modification of the tube 15. In this latter case the slender tube 19 may be provided at its lowermost end 19a (facing the powder in the container 12) with a cone-shaped member 2li or a gatherer, while its other closed end having a round head 20 which may have a plurality of dispensing holes 21. It is obvious, that in this case, the talcum powder from the container 12 may readily enter the tube 19 through the gatherer 20 to be delivered to the dispensing head 21.

It will now be recognized from FIG. l that my neck duster 1t? may be readily utilized in barber shops in the usual marmer. By means of the slender tube 15 a measured amount of powder will be automatically delivered to the bristles 14 of the brush. ln the event the powder in the container 12 becomes depleted, the barber may push the tube 15 slightly further out of the handle 11 as indicated by the dotted lines (A) in FIG. 2. ln the event there is too much powder in the container, t0 promote better delivery the tube 15 may be pushed further into the container as shown by dotted lines (B) in FIG. 2. While FGS. l to 3, inclusive, illustrate my dispenser tube 15 in its simplest form, the modification shown in FIG. 4 is an improvement. In this case to promote better delivery of the powder from the tube 19, the latter may be provided at one end thereof with the cone-shaped member or gatherer Ztl and at the other head with the powder dispenser head 21, with its powder dispensing openings 22. Although the dispenser tube 19 may be slightly more expensive to produce than the tube 15 (see FIGS. 1 to 3) by means of its gatherer 20 and the head 2.1 it may dispense talcum powder at greater efliciency. ln addition, because of the bulkiness of the gatherer 20 it may not come olf its mounting hole 23 in the base 24 when it is pulled.

A careful examination of the foregoing description in conjunction with the invention as illustrated in the drawing, will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty, sufficient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts, may be resorted to in actual practice, as long as no departure is made from the invention claimed.

Having described my invention, what I claim is the following:

1. A neck duster of the class described, comprising, in combination, an elongated hollow brush handle of cylindrical contour open at one end and closed at the other to form a powder container, an outer thread cut at its open end, a cover having a circular flange, an internal thread cut in said liange, said cover being threaded over the outer thread in said hollow handle to close said open end to form said powder container, means in said closedk end to mount a plurality of line bristles, a centrally disposed hole in said closed end communicating the outside with the vcontainer inside, a slender flexible tube functionally held in said opening and slideable therein, one open end thereof extending into said container with its other closed end extending outwardly among the bristles, ne holes in said outward end in said tube for dispensing powder from said container passing through the slender tube aforesaid. Y

ZQThe combination according to claim 1, and a plu-` rality of circular grooves drilled in said closed end facing outwardly and means for securing ne bristles in said grooves to forma neck duster.
